Answer:
A sexual reproduction..
a sexual reproduction is a type of reproduction which doesn't involves the fusion of gametes or change in number of chromosomes
Budding ..
a process by which new duplicate plant or animal begins to form it is mainly in plants
ex: amoeba binary fission
Asexual REPRODUCTION -Asexual reproduction is a type of reproduction which does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent.
BUDDING-Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. The small bulb-like projection coming out from the yeast cell is called a bud
EMBRYO-a baby, an animal or a plant in the early stages of development before birth
FERTILIZATION-The fusion of male and female gametes to form a zygote is known as fertilization
FRAGMENTATION-the process or state of breaking or being broken into fragments.
GAMETES-Gametes are an organism's reproductive cells. They are also referred to as sex cells.
HYPHA-each of the branching filaments that make up the mycelium of a fungus
OVULE-in plants that produce seeds) the part of the ovary that contains the female cell that becomes the seed
POLLEN GRAIN -each of the microscopic particles, typically single cells, of which pollen is composed. Pollen grains have a tough coat that has a form characteristic of the pollen-producing plant and which can still be recognized in some archaeological deposits.
POLLEN TUBE-a tube which grows when pollen lands on the top of the female part in the middle of a flower (stigma) to carry the male cell to the part that contains the female cell (ovule)
POLLINATION-Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma
SEED DISPERSAL-Seed dispersal is the movement, spread or transport of seeds away from the parent plant. ..
SEXUAL REPRODUCTION-Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes (haploid) combines with another to produce an organism composed of cells with two sets of chromosomes (diploid
SPORE-one of the very small cells like seeds that are produced by some plants and that develop into new plants
SPORANGIUM- cells or structures in which spores are produced. Ferns, fungi, mosses, and algae release spores from sporangium. Also called spore case
VEGETATIVE PROPAGATION-Vegetative propagation is an asexual method of plant reproduction that occurs in its leaves, roots and stem. This can occur through fragmentation and regeneration of specific vegetative parts of plants..
ZYGOTE-a cell that starts the process of forming a baby person or animal, formed by the joining together of a male and a female gamete
